Product Details

The Caliso 620K4 is a K-section Poly-V serpentine belt designed for reliable power transmission across automotive, commercial, and light industrial applications. Also referred to as a multi-rib or micro-rib belt, this 4-rib, 62-inch pitch length belt delivers smooth, efficient drive performance across multiple pulleys in a single continuous loop.

Key Specifications:

  • Belt Section: K (PK) — K-section Poly-V / micro-rib profile
  • Pitch Length: 62.0 inches (1574 mm)
  • Outside Circumference: approximately 62.75 inches
  • Number of Ribs: 4
  • Belt Width: approximately 0.56 inches (14 mm)
  • Rib Pitch: 3.56 mm (K-section standard)
  • Cross-Reference: FVP Poly-V Belt 620K4; also referenced as 4PK1574

Features & Benefits:

  • Multi-rib K-section construction combines the flexibility of a flat belt with the positive grip of V-shaped ribs
  • Suitable for serpentine drive systems powering accessories such as alternators, water pumps, power steering pumps, and air conditioning compressors
  • Designed to wrap smoothly around multiple pulleys — including backside idler pulleys — without cracking or glazing
  • Compatible with standard K-section (PK) grooved pulleys; not interchangeable with J-section or standard V-belt pulleys

When replacing this belt, confirm the section letter (K), pitch length (620 / 62.0 inches), and rib count (4) match the original to ensure proper fit and performance.

Good experience.

Check selection of tires. Easy search to find the exact tires I needed. And they were shipped in perfect timing. Thank you.

We were very pleased with the quality of the bumper we purchased and the customer service was superb. We received both the bumper and kit within 3 days. This is the first time we ordered from Dirt Everywhere and we would not hesitate to order from them again. Thank You for the great service !!!
